The series will follow the former University of Missouri football player on his journey into the NFL with the St. Louis Rams.

"We are honored that Michael is trusting us with his private journey in this moment that has not only made history, but will shape it forever," Winfrey said in a statement. "I am proud of the focus on authentic storytelling in our new documentary series format. The next real-life story we follow in 'The Untitled Michael Sam Project' promises to spark valuable, important discussion on life in America today. Acceptance and illumination start here."

The series will document the scrutiny Sam draws as he works to win a spot with the Rams.

"Like every player out there working to make a team right now, my focus is on playing football to the very best of my ability," Sam said. "I am determined. And if seeing my story helps somebody else accept who they are and to go for their dreams too, that's great. I am thankful to Oprah for her support and excited to work together."

OWN will partner with producer Craig Piligian's Pilgrim Studios and filmmaker Amy Rice ("Lindsay," "By The People: The Election of Barack Obama") to produce the series.
